I want to control the power-wire of another 5V powered device (s) using RPi GPIO. Potentially it will 8-10 of such devices, which I want to control. Each device needs 2-5 A (for example, strong LED flashlights). I thought to use an old ATX power supply, but the actual circuit isn't clear at this moment.
I thought to use SN74LS245N and then solid-state relay, but it seems overkill and something much simpler and cheaper could work as well.
All devices will have common ground wire. Therefore some buffer to protect GPIO and MOSFET could work well, I hope.
I will appreciate any ideas!
